    Subject2.4.29, e100 and a WOL packet causes keventd going mad
    Hi,

    we have about 70 P4 uniprocessor machines (some with Hyperthreading
    capable CPUs) running linux 2.4.29, which are woken up on the weekdays
    by sending a WOL packet to them. The machines all have a E100 nic with
    WOL enabled in the bios. The E100 driver is compiled into the kernel
    and not loaded as a module.

    If the machine which should be woken up is already running (because
    someone switched it on by hand), the WOL packet causes keventd to go
    mad and "use" 100% CPU:

    PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
    2 root 15 0 0 0 0 R 99.9 0.0 140:50.94 keventd

    This can be reproduced on any of the 70 machines by simply sending a WOL
    packet to it, when it's already running... No entry is made in the
    kernel log.

    The dmesg of an affected machine can be found at:
    http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-dmesg
    Our kernel-config is at:
    http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-generic-config
    lspci -vvv is at:
    http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-lspci

    We are using a kernel.org linux 2.4.29 kernel patched with the current
    autofs patch and ACL support.

    Regards,
    Michael
